Application filed June 15,

To all whomy t may concern e it known that we, WILLIAM KEARNS and ENRY P. CONNELLY, both citizens of the United States, and reside-nts of Detroit, county of Wayne, and State of Michigan,

ave invented a certain new and useful Apparatus for Refinishing Blemished Tires, of which the following is a full, clear, and eX- act description.

is invention relates to an apparatus for re-finishing blemished tires.

)wing to an insufficient quantity of rub- `With necessarily limit its scope, the invention eonsists brieiiy in introducing a filling strip 'tire and a core on curing, To conveniently introduce the stripaway from the core, strip smoothing members are associated therewith to .guide the strip and lay it flat directly upon the core. The apparatus is demountably anchored izo-axial with the core so that, upon rotation of the a stiip may be applied throughout the entire circumference of the core, if desired and as preferred. l

The preferred embodiment of the iiivent-ion is illustrated in the accompanying drawings in which:

ig. 1 is an elevation of a Acore stand or buck with the apparatus shown in working relation therewith, the core and tire appearing in sec lon, Fig. 2 is a similar elevation, partly in sec- 7011191113 CCeSS there/t0.

tion, of a part of the apparatus, the tool proper being shown in a position about to be engaged with the tire bead,

Fig. 3 is a fi'aginentar detail, and

Fig. '4 is a plan view of the apparatus complete, a part of the tire being broken away to better illustrate the construction.

In the drawings, 1 shows a stand to which is swivelled, as indicated at 2, an arm 3 on whose free end a core 4 is adapted to be supported for rotation in a horizontal plane with either of the sides uppermost for cony The core erably rotatable about a spindle 5 opposite ends are threaded nuts 6, collar 7 being preferably provided both of the nuts 6 the saine distance central plane of the core.

carrier indicated generally by the numeral 8 is adapted to be slipped over either of the nuts 6, portion 9 with a liexagonally or nut-shaped opening and an arm portion 10, which is adapted to be adjusted for different sized tires by the bolt and slot connect-ions indicated at l1. To the carrier 8 at 12 is fulcrumed a main lever 13 which has an abutment face or stop 14 adaptedI in the position shown in Fig. 2, to contact with an adjacentvface of the arm portion l() and to limit inward swinging movement of the lever. The arm portion 1() and the main drilled as indicated locking pin 17 for relative the carrier position shown in on whose a spacing to locate from the Figure 1.

At the free end of the main lever 13 on a pin 18 is fulcrumed an auxiliaryiand hand operable lever 19 normally pulled upon by a lightly tensioned coiled spring 19. `he pin 18 passes through the forked extremity 19 of the hand lever, which latter is loosely pinned as indicated at 20 interinediately of a member 2l whiclisupports a bead engaging element 22, preferably in the form of a freely rotatable roller and. grooved or notched to hold the heel of the bead with certainty.

The bead engaging element 22 as thus supported is adapted when the pin 17 is Withdrawn, to be lowered to the position shown in FiO. 2 and to be inserted in any convenient manner under the heel of the tire 4.- is prefbead. By pulling on the hand lever 18 to the left, as shoivn in Fig. 2, the tire bea-d may be pulled slightly away from the core when the rear portion 21 oi' the member 21 jams against the main lever 13. Thereafter continued pull upon the hand lever 19 turns the main lever 13 and element 22 as one piece about the ulcrum 12. When the holes 15 and 16 are in registration, the locking pin 17 may be inserted to hold the tire bead in the position shown in Fig. 1. In this position, an operative may freely brush cement on the exposed surface of the core 4 by turning the latter on the spindle 5.

A filling strip or pad, ot' suitable proportions, say, about two inches by oneeighth of an-inch in cross sectlon, and of any suitable material, such. as mushn strips secured together by frictioning their opposed meeting faces, may then be introduced. Conveniently, this may be done by threading the stripy between the smoothing members 23, one of which, as indicated at 24 in Fig. 4, is preferably of the concave shape illustrated. The smoothing` members may be mounted in a channel plate 25 which is riveted Von one end oi a bar 26 that is bent, as shown, and at its opposite end pro- -vided with an open-ended slot 27 for detachable mounting on a shouldered stud 28. Intermediately, the bar 26 is provided with a lug 29 for engagement. with the side o'l the member 21 and prevention ot rotation when the core is turned. Obviously, by introducing a filling strip, suoli as is indicated at 30, through the smoothing members 23, thesame may be laid between the core and tire, which is held locally spaced therefrom, through any desired extent of the circumference, the strip adhering tothe cement that has been previously applied to the core.

It will thus be seen that We have provided a simple and eiiicient apparatus for cementing a core and interposing a filling strip between it and a blemished tire so that the latter., on. being subsequently mounted 'in a mold, may have the blemished portion, or portions, of its outer surface on one or both of its sides forced to take the exact outlines V of the mold. Consequently, of course, the

blemished tire as re-finished appears perfeet. A cure for twent minutes at 30 .y pounds steam pressure wlll ordinarily suflice.

flhe construction above described in detail may be varied in many Ways Without ldepartingfrom the .principles of the invention and reference should, therefore,` be made .to the accompanying claims for an understanding of its scope. While the core is preferably rotatable, obviously, it could be held stationary and the tool rotated or moved ciroularly and coneentrically thereof.

`Having thus described our invention,

what we claim and desire to protect by Letters Patent is:

1. In an apparatus for preparing blemished tires on cores for a re-linishing treatment, in combination, a tool adapted to hold a portion of a tire away from the core, and

.means for supporting the tool and core in co-operative relation permitting concentric circular movement of the one relative to the other.

2. In an apparatus `for preparing blemished tires on cores for a re-finishing treatment, in combination, a too-l adapted to hold a portion of a tire away from the core, mechanical means 'for maintaining said tool in a pre-determined spaced relation from the core and thereby spreading the tire Wall from the core, and means for supporting the the tool and core in cooperative relation permitting concentric circular movement of the one relative to the other.

ln an apparatus for preparing blemished tires on cores for a re-inishing treatment, in combination, a bead engaging element, articulated members i'or supporting said element including a manually opera tive lever loosely pinned thereto, and means for supporting the members and core and permitting rotation oi the core.

5. ln an apparatus forprepa-ring blemished tires on cores for a re-linishing treatment, in combination, a bead engaging roller, a member supporting the same, a lever articulated to said member and having a relatively fixed fulcrum, a carrier for said levers iulcrum adapted to be supported laterally ci' the core, and means tor locking 'the lever to the carrier to hold the roller spaced 'from the core, said core and carrier being relatively movable about the axis of the core as a center.
